摘要
针对电力信息系统的单体架构处理信息量较小,无法全面监测电网链路信息的问题,提出基于微服务架构的电力信息系统的全链路监控技术.利用压缩感知算法建立测量与感知矩阵,完成信号重构;采集全链路信息,使用连续小波变换方法对监控信号降噪处理.构建微服务架构,通过纵向与横向两个维度实现全链路监控.实验结果表明,该方法监控到结果和人工注入的异常数据包数量完全一致,能够实时、准确地监控电力信息系统线路中的电流及电压数据.
Aiming at the problem that the single structure of power information system has a small amount of processing information and cannot comprehensively monitor the grid link information,a full-link monitoring technology of power information system under a micro-service architecture was proposed.In order to complete the reconstruction of signals,a compressed sensing algorithm was used to establish the measurement and perception matrix.In terms of the collected full-link information,a continuous wavelet transform method was used to perform the noise reduction processing of monitored signals.The micro-service architecture was established,and the full-link monitoring was realized along both vertical and horizontal dimensions.Experimental results show that the monitoring results of the as-proposed method are completely consistent with the number of abnormal packets obtained by artificial injection,and the as-proposed method can accurately monitor the current and voltage data of power information system in real time.
